Lolita the parrot can sing the song "Bodies" by the metal band Drowning Pool. Here's a selection from the lyrics:
One - Nothing wrong with me
Two - Nothing wrong with me
Three - Nothing wrong with me
Four - Nothing wrong with me
One - Something's got to give
Two - Something's got to give
Three - Something's got to give
Now
Let the bodies hit the floor
Let the bodies hit the floor
Let the bodies hit the floor
Let the bodies hit the floor
Let the bodies hit the floor
Let the bodies hit the floor

I pet sat for a couple of birds once (and a menagerie of other animals) and the parrot was the best- he knocked on the door (I opened it before I caught on), did the phone ringing, yelled at the other animals, had 1-sided phone conversations and repeated his owners fights. He also mimicked one of the other birds squawking and then yelled at him. Best vacation job ever!
